How are those vitamins working for ya? Personally I do take daily vitamins. It seems there is always something new coming out that is supposed to be the best for you. About 2 years ago I added vitamin D to my handful of daily supplements. But now it seems it’s getting harder to trust the people that are making the pills, capsules, liquids, & ointments.

Here is the latest report from

What's in your vitamin supplement? It could be more or less than you think, according to the latest study to show that what's on a supplement label is not necessarily what's in the bottle.

Researchers who tested vitamin D pills sold in stores found they contained from 9% to 140% of the doses listed on labels, according to a research letter published Monday in JAMA Internal Medicine. Though none of the pills was likely to be dangerous, some contained too little of the vitamin to effectively treat someone with a deficiency, the researchers say.

"We found the potency of these vitamin D supplements varied widely," says Erin LeBlanc, an endocrinologist who led the study at the Kaiser Permanente Center for Health Research in Portland, Ore.

Other studies have found similar variations in other supplements. For example, more than one-third of multivitamins tested by in 2009 were contaminated or contained significantly more or less of some ingredients than their labels claimed. The company also recently tested vitamin D samples and found some mislabeling, it says.

About half of adults in the USA take dietary supplements, spending $30 billion a year, according the Office of Dietary Supplements, National Institutes of Health. Vitamin D is particularly popular. The vitamin is essential for bone health and may have other benefits, but most people get enough from food and sun exposure, according to the Institute of Medicine.
